如何解决Jenkins声明式管道。块中的条件语句?

的确,您当前不能when在全局post块中使用。When必须在stage指令内使用。

使用是一种合理的选择if else,但是您需要在声明性管道中使用脚本编写的块来完成此工作:

pipeline {
agent any

parameters {
string(defaultValue: "master", description: 'Which branch?', name: 'BRANCH_NAME')
}

stages {
stage('test'){
steps {
echo "my branch is " + params.BRANCH_NAME
}
}
}

post {
success{
script {
if( params.BRANCH_NAME == 'master' ){
echo "mail list master"
}
else {
echo "mail list others"
}
}
}
}
}

参数为master时输出

[Pipeline] {
[Pipeline] stage
[Pipeline] { (test)
[Pipeline] echo
my branch is master
[Pipeline] }
[Pipeline] // stage
[Pipeline] stage
[Pipeline] { (Declarative: Post Actions)
[Pipeline] script
[Pipeline] {
[Pipeline] echo
mail list master
[Pipeline] }
[Pipeline] // script
[Pipeline] }
[Pipeline] // stage
[Pipeline] }
[Pipeline] // node
[Pipeline] End of Pipeline
Finished: SUCCESS

参数为“ test”时输出

[Pipeline] {
[Pipeline] stage
[Pipeline] { (test)
[Pipeline] echo
my branch is test
[Pipeline] }
[Pipeline] // stage
[Pipeline] stage
[Pipeline] { (Declarative: Post Actions)
[Pipeline] script
[Pipeline] {
[Pipeline] echo
mail list others
[Pipeline] }
[Pipeline] // script
[Pipeline] }
[Pipeline] // stage
[Pipeline] }
[Pipeline] // node
[Pipeline] End of Pipeline
Finished: SUCCESS
@H_404_13@

为了使它更加简洁,您可以将脚本作为函数调用

pipeline {
agent any

parameters {
string(defaultValue: "master", description: 'Which branch?', name: 'BRANCH_NAME')
}

stages {
stage('test'){
steps {
echo "my branch is " + params.BRANCH_NAME
}
}
}

post {
success{
getMailList(params.BRANCH_NAME)
}
}
}

def getMailList(String branch){
if( branch == 'master' ){
echo "mail list master"
}
else {
echo "mail list others"
}
}

解决方法

有一个詹金斯管道。构建成功时需要/想要发送电子邮件。通过电子邮件将所有分支的电子邮件发送到 maillist-1, 并将master分支的构建过滤到
maillist-master
我尝试使用ifwhen语句步骤,但它们均在后期阻止中失败。

pipeline {
agent ...
stages {...}
post{
success{
archiveArtifacts: ...
if( env.BRANCH_NAME == 'master' ){
emailext( to: 'maillist-master@domain.com',replyTo: 'maillist-master@domain.com',subject: 'Jenkins. Build succeeded :^)
